ERROR: Persistence already in use, Reload this gateway when MQTT Broker comes UP

I'm running 0.0.3.Alpha2 on a linux/ubuntu system and connecting to another system on my network running Mosquitto. I have added my gateway into mycontroller but its giving me an error "ERROR: Persistence already in use, Reload this gateway when MQTT Broker comes UP".

Could someone please eleborate on what this actually means? I have no other controller alive at the moment and therefor its an internal error on this system, from what I can work out anyway.

@jkandasa - I have disabled the built in MQTT broker, through the web UI where you have put the slider for the MQTT broker, that is turned to the off position. Should i have disabled it in any other way, command line or anything? I'm running it on a Linux box.

Thank you for the detailed log. We have an option in GUI only to stop/start MQTT broker.
Looks like you have entered MQTT Borker host as only 192.168.0.21 on gateway settings, which is wrong. You have to feed as tcp://192.168.0.21:1883. Kindly remove your old gateway entry if any. and add new entry with tcp://192.168.0.21:1883.

Not sure why its saying that it was on 192.168.0.21 - Every time i went back to check it, it was automatically taking away the tcp:// too. However, i don't recall putting the port number after it. I think that was specified under it. I will attempt this and report back.

Do you have any sort of guide/walk through for adding new nodes as all the options like "Registration Status", "EUI", "Firmware", I feel could be explained a little to people tbh. Obviously, users could go looking around the internet to find out what you actually mean by those labels but tooltips or some guide/walk through would be nice to add in. Just to let you know

Okay, so i have MyController working and seeing my gateway with the sensor attached. However, i have obviously setup the sensor incorrectly as it wont relay messages back to it. So, do you have some sort of walk through or guide to add a mysensor node/sensor to the controller properly please?
